I RA IL-JOilYE EQ To all whom it may concern-.- 1 Be it known that I, WL ocK V; Zs nnn KEE, a citizen of the United States, residing atDetroit, in the county of lVayne and State of Michigan, have inventedcertain-new and useful Improvements in Rail-Joints, of which the,following is a specification, reference being had to the accompanyingdrawlngs. I

- This invention relates to certain improve ments in'rail joints and hasrelation more particularly to a. device of thisgeneral character whereinis included a treadbridge piece and it is an object-o-ftheinventiontoprovide a novel and improved rail joint wherein pounding issubstantially "en'- tirely eliminated as the rolling stock passesthereover; V a 5 I It is also an object of the invention-"to provide anovel and, improved rail. joint whereina tread bridge piece 'co-actswith' the meeting ends of therailsand partially straddles the webportions thereof together as willxbe hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitelyclaimed.

In order that my invention may be the better understood I will nowproceed to de scribe the same with reference to the accompanyingdrawings wherein:

Figure 1 is a View in top pianillustrating a rail joint constructed inaccordance with an embodiment of my invention;

Fig. 2 is a view in side elevation'of my improved joint with one of thefishplates or splice bars removed and the co-acting bolts shown insection;

Fig. 3 is a sectional view taken substan tially on the line 3-3 of Fig.1;

Fig. 4 is a View in perspective of one of the fishplates or splice barsas herein employed;

As herein disclosed thera'ils R aire 'ofa ny o'rdinary or suitableconstruction and'for'a short distance ba'cli -fromfea'ch-end the treadof each of the rails isi cut-awayas indicated a t-1 said cut 'portioaextending slightly with in the upper portion-of the web of therail'.'lhe cut through tread of each of the rails is' preferably diagonalas-intl icated at 3;

The-'trea'dbridge piece'l compris s a tread is l of the sameconfigurationwi'n cross section as the treads of theI-rails R- d is fo fa length substa ti lly equal to; combined length of the cutawayportions: 1 at -the' meeting ends of the railsa Asis illustratedparticularly in Fig: 3 the tread bri'dgepi'ece T'- is initially, of alength slightly less than the combined length of the cut awayflpoitis'ons 1 iii-order tocoanpensate for expansion. The opposite ends 50fthe tread bridge piece Tare also: cut diagonally to. correspond with thecuts. 3'in the treads of the rails 'B so that when the tread. T is inapplied or. assembled position-a continuous tread is affordednotwithstanding .the space" allowed for expansion, as V will be readilyunderstood Depending from the tread bridge piece T are ithe transverselyspaced flanges 6i e-X'-' tending the entire length of the tread bridgepiece 10: and which area'd'apted to overlie'the opposite faces of theweb's 2 oftherai'l's'R. The flanges 6 are each: of. ai width less thanthe width or height of the webs 2 of the rails as isparticularlyillustrated in Figs.

2- and 3 of the accompanying drawings. Each of the flanges 6 adjacentits opposite ends is provided with the openings 7 adapted to registerwith the openings 8 produced in the webs 2 of the rails below the cutaway portions 1 thereof.

Co-acting with he meeting ends of the rails and arranged at eachsidethereof is a flshplate or splice bar B. The splice bar B includes aweb portion 9 provided along its upper marginal portions .and at itsopposite ends with the inwardly directed flanges 10.

The inner ends of the flanges 10 are spaced apart, as at 11 a distancesubstantiallyequal t0 the length of the tread bridge piece T so that theadjacent flange 6 of the bridge piece T will afford no obstruction tothe application of the fishplate or splice bar B into applied position.The upper edge of the web 9 and the flanges 10 preferably engage the uder faces of the'tread T of the meeting ends of the rail while the lowermarginal portion of the bar B is provided with an Each of the fishplatesor splice bars B below the space 11 afl'orded between the flanges 10 isprovided with the openings 17 adapt-- ed to register with the openings 7and'8 hereinbefore referred to and insertible through each set ofregistering openings 7, 8 and 17 is thebolt 18 having co-actingtherewith a clamping nut 19. As is particularly illustrated'in Fig. 1 itis preferred that the bolts 18 be oppositely directed.

The fishplates or splice bars B when in applied position and engagedwith the bridge tread piece T as hereinbefore disclosed through themedium of the bolts 18 and coacting nuts 19'serve to effectivelymaintain the bridge tread piece '1 in applied position although it hasbeen found of advantage to provide the outer end portions of each of'thefishplates or splice bars B with the openings 20 adapted to registerwith the openings 21 disposed through the web portions 2 of therails'inwardly of the cut away portions 1.

Directed through the registering openings 20 and 21 are the bolts 22havingco-acting therewith the clamping nuts 23. It is also preferredthat the bolts 22 be reversely directed and also reversely directedrelative to the adjacent bolts 18.

- From the foregoing description, it is thought to be obvious that arail joint con structed in accordance with my invention is Games of?this patent may be obtained for particularly well adapted for use byreason of the convenience and facility with which it may be assembledand operated and it will also be obvious that my invention issusceptible of some change and modification without materially departingfrom the principles and spirit thereof and for this reason Idonot wishto be understood as limiting myself to the precise arrangement andformation of the several parts herein shown in carrying out my inventionin practice except as hereinafter claimed.

I claim: o V In a rail, joint, the combination of meeting ends of railshaving their tread portions cut away, a tread bridgepiece fitting withinthe cut away portions of the treads, said bridge piece being providedwith transversely spaced flanges overlying the opposite faces of thewebs of the meeting ends of the rails, splice bars co-acting with theopposite sides of the webs of the rails and overlying the dependingflanges of the tread piece, and

fastening members disposed through the splice bars, the flanges of thetread bridge piece and the webs of the rails, said splice barscontacting with the base flanges of the rails and the under facesof thetreads of the rails, the upper marginal portions of the splice bars.being provided at their opposite end portions with longitudinally spacedand inwardly directed flanges, the space between said flanges beingsubstantially equal to the length of the tread bridge piece,"the flangesE of the tread bridge piece being arranged within said spaces. r

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.
